PETG heat shrink label

  PETG (Glycol-modified Polyetthylene Teraphthalate) is an amorphous plastic resin of the polyster family. Due to its 80% shrinkage, highest among all shrink sleeve material, PETG is an ideal solution for container shrink film that have complex geometries and require superior printability. Compared to other material, PETG resin is much more environmentally friendly making it a perfect solution for companies looking to switch from more harmful materials such as PVC. Since PETG's shrinkage occurs at a lower temperature than material like PVC and OPS, there is the added benefit of higher energy efficiency and productivity. Ordinary polyester is a crystalline polymer, and ordinary PET film can only achieve a thermal shrinkage rate of less than 30% after special processing. To obtain polyester films with higher thermal shrinkage, modification is also necessary. That is to say, in order to prepare polyester films with high thermal shrinkage, it is necessary to copolymerize and modify o…
